To all whom it may concern:

Be it known that I, HA RY DINHOFER, a.

citizen of the United States, and a resident of the city, county, and State of New York, have invented a certain new anduseful Improvement in Processes and Blanks for.

" to be followed in forming said ring.

Heretofore rings, when made of thin sheet metal, have consisted of a number of small sections, such as shank sections, sides and a top, and these sections had to be joined or soldered together to form the complete ring. This necessitates exceptional skill and care on the part of the workman to enable him to produce a ring of high grade workmanship and finish. It also increased the amount of work required to produce the ring due to the number of soldered joints required to connect together the various parts.

By the use of my improved ring blank and the method to be followed in bending and connecting together the integral parts of the blank, I produce a ring from a single section of metal. This enables the ring to be made with rapidity, and as the various elements or parts of the ring are formed as an integral part of a single blank, proper fitting and uniting together of the respective parts is assured whereby a ring of high class construction and finish may be readily made without difficulty or waste of material. a With these objects, and any other objects which may hereinafter appear, in view, I have devised the arrangement of parts hereinafter set forth and more particularly pointed out in the claims appended hereto.

Reference is to be had to the accompanying drawing, forming a part hereof, in

which- Figure 1 is a plan view of one form of blank from which my improved ring may be made;

Figure 2 is a side elevation of a ring made from the blank shown in Figure 1;

Figure 3 is an edge view of the ring shown in Figure 2;

Figure 4L is a sectional View on the line 1923. Serial No. 635,908.

4c-4: of Figure 1, looking in the direction of the arrows;

Figure 5 is a plan view of another blank for forming a pronged ring; and

Figure 6 is an edge view of a ring formed from the blank disclosed in Figure 5.

Throughout the various views of the drawings, similar reference characters designate similar parts.

Referring to the embodiment of my invention asdisclosed in Figures 1 to 4. The ring is produced from a single strip or section of substantially thin metal, such as platinum, gold or the like. The strip is preferably provided with a central portion, as indicated at 1, which is intended to form the top of the ring. I have shown this portion of the blank perforated as at 2 fcm the reception of stones.

Extending from opposite sides of the top 1 is a. pair of elongated portions 3, which are united together to form the shank of the ring and will therefore be hereinafter referred to as the shank portions.

Extending from the longitudinal side edges of the top 1 is provided a pair of wings or sections 4 which form the sides of the ring. Inasmuch as the shank portions, top and wings are stamped from a single section of metal, it will be obvious that such parts are integrally connected.

For the purpose of simplicity in illustration I have shown the parts unornamerited but it will be obvious that the blank may be pierced or perforated with any suitable design or it may be set with gems as desired.

To form the ring shown in Figures 2 and 3 from the blank disclosed in Figure 1, the parts are bent or folded upon the lines 5, 6 and 7. This brings the edges 8 of the sides 4: into contact with the side edges 9 of the shank portions. The meeting edges 8 and 9 are soldered together, and the shank portions 3 are bent around so that their ends 10 and 11 come together and these ends are soldered or joined as at 11*. The ring. thus produced is polished and finished ofi in the conventional manner.

The same method of procedure is followed in producing the ring shown in Figure 6 from the blank disclosed in Figure 5 except that in that particular form of blank the prong portions 14 are bent upwardly andjoined together. The sides for the ring are shown at 12 and the extensions 13 on the shank portions 3 constitute the ends.

I have herein shown and described two forms of blank and the process to be followed in forming my improved ring therefrom. It will be obvious that many other forms may be produced without departing from the spirit of my invention.

lVhat I claim is 1. An article of the class described com prising a blank for a finger ring consisting of a fiat strip of metal having shank portions, a top disposed between said shank portions, and laterally extending wings pro- Ijecting from the sides of said top and adapted to have their side edges united to the shank portions.

2. An article of the class described comprising a blank for a finger ring consisting of a flat metal strip having shank portions, and an integral top portion and an integral pair of wings extending from sides of the top.

3. An article of the class described comprising a blank for a single piece finger ring consisting of a flat-strip of substantially thin metal having a central portion adapted to form a top for the ring, integrally formed extensions projecting from opposite sides of the top and adapted to form the ring shank, and a pair of wings extending from opposite sides of the top intermediate of the shank portions, said wings being adapted to have their side edges bent and brought into contact with the shank portions and connected thereto to form sides for the ring.

- 1. The process of forming a finger ring consisting of producing a flat strip of metal having shank portions, a top and side wings integrally connected, of folding said shank portions and side wings away from the top to bring the side edges of said side wings into'contact with the edges of the shank portions and uniting the meeting edges of the wings and shank portions together.
